Famous Documentaries

Above are some examples of documentaries at which I have been looking for inspiration. Mainly for shot ideas, in particular the Johnny Cash documentary has a lot of close up shots and one on one interviews that I can use to base my documentary layout on. The bottom documentary Race to Nowhere gives me more of an educational based look and feel so will give me inspiration for my in between and establishing shots. The top two very famous documentary scenes are mainly about camera angle variety and handheld camera techniques - both of which I need to consider in my documentary making.
